The second-hand market refers to the buying and selling of used goods, which can include items like clothing, furniture, electronics, and books. This market allows consumers to purchase items at lower prices compared to new products, promoting sustainability by extending the life cycle of goods. Many platforms facilitate the second-hand market, such as thrift stores, online marketplaces like eBay and Facebook Marketplace, and local garage sales. This market benefits both sellers, who can declutter and earn money, and buyers, who can find unique items and save money while reducing waste.
